The 22nd Regiment was originally raised in July 1950 as a unit of the "supplementary reserve", which was formed within the Citizens Military Force to utilise the personnel and resources of various civilian government organisations to raise a military construction capability. The regiment's first commanding officer was Lieutenant Colonel I.J. O'Donell and its first annual camp took place at Puckapunyal, with 20 officers and 220 other ranks taking part. The Regiment currently consists of a regimental headquarters (RHQ), a works section and three engineer
squadrons. RHQ is based in Dublin Road, Ringwood East, along with 8th Combat Engineer Squadron. 105th Construction Squadron is based at
Oakleigh, Victoria, while the 10th Combat Engineer Squadron is based at
Newborough in
Gippsland, Victoria. The Regiment has been providing construction and works support to nearly every
Army Aboriginal Community Assistance Program (AACAP) task since the Federal Government directed these tasks to begin in 1997. The Regiment has also been involved in providing Defence Aid to the Civil Community since the 1960s, in particular supporting the emergency services and local communities in disaster response. Over the past 10 years the Regiment has led the ADF response to Victoria's bushfires, in particular the 2003 Alpine Fires, the 2006 Gippsland Fires, and in 2009 it was initially the lead element in the Black Saturday fires. Since the Regiment was raised it has deployed Army Reserve engineers to Papua New Guinea, South Vietnam, Bougainville, East Timor (Timor L'este), Solomon Islands and Afghanistan. == Organisation ==
